Police believe she left the lagoon at around 3.55pm. Her body was found by a dog walker, by the ABC steps at around 4.15pm.

On Friday her elder sister Anne Cleave and younger brother Colin Frost paid tribute to Elsie’s life in a moving memorial service at the church.

Colin, wearing a yellow ribbon broach featuring a picture of his sister, read aloud “The Knock on the Door”, a short story he had written about his family and what happened when they received news of Elsie’s death.

He said his sister Elsie was like a third mum to him, he said: “Mum three was taken away from the little boy but not so he could see her each night, like his mum when she returned from work, not like he could go over and visit her like he could with mum two [Anne].
